Why Choose the ABB E2.2S 2500 Ekip Touch LSIG 3p WMP Air Circuit Breaker?
The ABB E2.2S 2500 Ekip Touch LSIG 3p WMP, order code 1SDA072426R1, is a high-performance three-pole air circuit breaker (ACB) moving part from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage electrical distribution systems. Combining the E2.2S frame with a 2500 A rated uninterrupted current and ABB's Ekip Touch LSIG electronic trip unit, it provides comprehensive overload, short-circuit and ground-fault protection for high-current industrial, commercial and infrastructure power networks.
This breaker uses a withdrawable construction for integration with a compatible Emax 2 fixed part, supporting efficient inspection, servicing and replacement within switchboard installations. Its Ekip Touch LSIG solid-state electronic release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection, while the Touch interface supports straightforward configuration and supervision of the protection functions.
The E2.2S 2500 provides an ultimate short-circuit breaking capacity of 85 kA at 400/415 V AC and 66 kA at 690 V AC. With a 2500 A current rating, three-pole configuration, integrated ground-fault protection, four auxiliary contacts and withdrawable moving-part construction, the 1SDA072426R1 is particularly well suited to main distribution, incomer and high-current feeder applications.
